Definition

Legg-Calve-Perthes disease is a childhood condition associated with a temporary loss of blood supply to part of the hip joint. Without adequate blood flow, a process can occur in which the bone becomes unstable, and may break easily and heal poorly.

Legg-Calve-Perthes disease typically affects one hip, but sometimes it develops in both hips. Although Legg-Calve-Perthes disease can affect children of nearly any age, it's most common among boys ages 4 to 8.

Children who develop Legg-Calve-Perthes disease when they're very young often have the best outcomes. The younger your child, the more time there is to reshape the affected hipbone. Most children with Legg-Calve-Perthes disease do well in the long run.
